  1. Do now: • What is blood doping? • Generally, blood doping refers to the use of performance-enhancing drugs (PEDS) that are administered into an athlete's blood system to increase the oxygen-carrying capacity of his blood by increasing the amount of red blood cells in his body. "Elevated blood levels, gained by using EPO or other blood doping methods give a huge advantage because oxygen-rich blood cells allow the muscles to work for longer, and to recuperate better after an extreme effort," says former U.S. Postal Service Team doctor Prentice Steffen.
